@wakame Of course, microservices aren't a silver bullet (since there are no silver bullets).
In particular, they tend to push complexity from code/development and into sysadmin/operations. This leads to the automation of operations and thus devops.
The paradigm also gets a lot of misuse and improper use, which attracts undue criticism.
Also, even if it turns out it's not what you're looking for, the lessons learned would be important to the development of your concept.
